Golay Cell

Golay Cell is an opto-acoustic detector designed for operation in the spectral range 0.02-20 THz. It is equipped with a 6 mm diameter polyethylene input window that provides for high transparency at frequencies up to 20 THz. Black polyethylene input windows are available as an option to cut off optical radiation. Golay Cell includes a build-in preamplifier. Operation of a Golay Cell requires a three-unit power supply delivering the following: +15 V, -15 V and 32 mA. Such a power supply is also available as an option Performance of Golay Cells is detrimentally affected by mechanical vibrations. Addressing this problem, our Golay Cells are mounted on proprietary vibration-isolating bases.
